Hi, Dearanyone could help me? when I use Custom blacklist to block www.facebook.com it's working fine, but anyhow someone still can access it by using smart phone.I hope anyone could help me to solve this problem.Thank in advance.

Try blocking facebook.com instead of www.facebook.com, but the possibility is that smart phones ignore filtering via proxy, as there is no settting for proxy in some phone versions of Android for example.

Therefore the only possibilty is to blocked the smartphones completely.
